Water revitalization for a space station can consist of membrane filtration processes and a distillation process. Water recycling equipment using membrane filtration processes was manufactured for ground testing. It was assembled using commercially available components. Two systems for the distillation are studied; one is an absorption type thermopervaporation cell and the other is a vapor comp...
Membrane distillation (MD) and osmotic distillation (OD) are emerging athermal processing techniques of great interest in agro-food production where the most part of products is sensitive to thermal treatments. With respect to conventional methods, MD and OD are competitive alternatives, able to work in an environmental-friendly and cost-efficient way, for preserving the nutritional and sensori...
s The use of brackish water in the Saloum Delta in Senegal can be made by combining the processes of desalination as a source of solar energy, usually thermal and photovoltaic processes for membrane distillation. But the demand for energy is growing; the use of solar energy can be a good solution, given the high solar potential in these areas. Different experiences around the world have shown t...
The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
The abundant resource of low-temperature heat sources (≈80–120 °C), e.g., low-concentration solar collectors or shallow geothermal wells, hold huge potential to be a renewable energy supply. A proposed method for harnessing such low-grade is use the distill solution and then utilize produced concentration difference generate work, by means salinity gradient power (SGP) technologies. In this app...
Abstract Membrane distillation (MD) is a novel desalination technology that has potential to produce distilled quality water from high salinity brine streams. The driving force for MD the vapor pressure difference across hydrophobic membrane resulting in transfer of hot cold side. This contacts surface and condenses distillate. paper reviews recent and/or multi-year research programs focused on...
